SVN to Git using git svn - keeping git updated

I am migrating from SVN to git using the git-svn plugin.

I cloned the SVN repo with history and that worked. I was able to push into my Gitlab 'main' branch in my new repository. And when I do a git svn fetch I see the changes from my SVN repo. And doing git log --all shows the revisions.

But nothing I do seems to push the new change up to the git Repo.

git branches (I did not need to migrate any tags or branches other than trunk)

~/GitMigration/Blah-Main $ git branch
* main
~/GitMigration/Blah-Main $ git branch -r
  origin/main
  origin/trunk

The original push into the git repo main branch I had to do a -f but even that doesnt seem to do anything

~/GitMigration/Blah-Main $ git branch -a
* main
  remotes/origin/main
  remotes/origin/trunk
~/GitMigration/Blah-Main $

~/GitMigration/Org-Main $ git push origin main
Everything up-to-date

svn-remote.svn.url=https://svn.com/Org/svn
svn-remote.svn.fetch=Org/trunk:refs/remotes/origin/trunk
svn-remote.svn.branches=Org/branches/*:refs/remotes/origin/*
svn-remote.svn.tags=Org/tags/*:refs/remotes/origin/tags/*
svn.authorsfile=/Users/user/GitMigration/authors.txt
remote.origin.url=https://gitlab.com/org/org-main.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
branch.main.remote=origin
branch.main.merge=refs/heads/main

The problem is that you are pushing main (local main), which is not the right branch to push. Given that your svn branch is (apparently) origin/trunk, you should run this to have it show up in origin/main:

git push origin origin/trunk:main

The trick to understand here is that to git, it's all about commits.... and branches are just pointers to commits. The svn branch is not (local) main, it's origin/trunk, so, after running git svn fetch to sync up, what has moved is origin/trunk and so we need to push that commit to origin/main... hence the command I used there (breaking up that command, it is: git push <some-remote> <some-commit>:<remote-branch>).

Side note:

It bugs be a little bit that you set git-svn to map the svn branch to origin, should probably keep the svn repo and the real git repo as different remotes (so that the svn branch could show up as svn/trunk, for example)... if that were the case, after git svn fetch, you would run:

git push origin svn/trunk:main

Which looks a lot better but, as we can see, it's possible to keep it the way you have it.
